Four paramedics working at the Bonnaroo Music and Arts Festival are being treated for possible carbon monoxide poisoning. The incident took place on Monday.

Investigators revealed that the four paramedics were using a generator to power the RV where they stayed. One of the paramedics woke up and called for help. Three of the four patients were airlifted to a hospital, and the fourth paramedic was transported to a nearby facility via an ambulance.

Spokesperson Releases Statement

Lucky Knott, a spokesperson for the Coffee County Sherriff's Office, confirmed that the four paramedics are not employed by Coffee County EMS.

"It looks like the exhaust somehow was blocked. They are just very, very fortunate. Right now, we are in hopes that all four will survive," said Knott.

As of early Monday, 32 festivalgoers were taken to hospitals by ambulance while five other concertgoers were airlifted via medical helicopter. Majority of the patients suffered from heat-related issues.

Man Dies At Bonnaroo

Prior to the four paramedics' case, one festivalgoer also died potentially due to heat stroke. Michael Craddock Jr. was found dead in his vehicle on Friday.

Sherriff Steve Graves confirmed that there is no foul play in the death of the 32-year-old. Craddock's body was also sent to the medical examiner's office and his official cause of death has yet to be revealed.

Eminem Receives Criticism

In related news, more controversies surround Bonnaroo Music Arts and Festival after its headliner, Eminem, used common gunshot-like sound effects during his set on Saturday night.

Some of the festivalgoers ducked and covered after they thought that the gunshots they heard were real. However, it was later on revealed to be part of Eminem's performance of "Kill You." The track is featured in the musician's 2000 album The Marshall Mathers LP.

"I'll kill you," Eminem sang before the gunshots were played.

Eminem's rep, however, claimed that the singer did not use gunshot sound effects during his performance. Rather, it was a pyrotechnic concussion that creates a loud boom-like sound. The rep also said that the same technique has been used Eminem during his live shows for the past 10 years.

Despite the explanation, some festivalgoers were still displeased with Eminem's set at the festival. YouTube star Andrea Russett said she felt traumatized.

"I hate to be the one to say it, but being someone who suffers from very mild PTSD, it was EXTREMELY irresponsible and distasteful to end songs w the shotgun sound effect," wrote Russett.
